##### Title:

Species distribution in the Danube - Black Sea, Elbe - North Sea, Guadalquivir - Atlantic Ocean and Po - Adriatic Sea river-to-sea continuum.



##### Description:

This dataset contains species number of macrozoobenthos, fish and phytoplankton communities according to habitat assignment for the Danube - Black Sea, Elbe - North Sea, Guadalquivir - Atlantic Ocean and Po - Adriatic Sea continuum. Each record summarizes species counts and their relative contribution at each kilometer.

This repository contains the derived results of the MARCO-BOLO Deliverable 3.3.
The materials provided here do not include the original/raw dataset, but only processed outputs generated from it.



##### Contents:

MBO_Report_Species_Distribution.csv - Aggregated species distribution data of all four river-to-sea systems.



##### Columns:

River – Name of the river-sea system where samples were collected (Danube, Elbe, Guadalquivir, Po).
Taxon_Group – Biological group analyzed (Macrozoobenthos, Fish, Phytoplankton).
Km – River kilometer indicating the sampling location.
First_Habitat – Habitat type according to where species first occured in the river-to-sea continuum (Freshwater, Transitional, Coastal, Marine).
Species_count – Number of species observed for the given habitat type.
Total_species – Total number of species recorded across all habitats at the site.
Percent – Percentage contribution of the habitat type to the total species count.
